Opening Day is always the most anticipated day of grouse season. Excitement for the hunter and for the dog. That first big grouse flushes.....you shoot......and miss!! Your Gordon looks at you like, "What the heck??" To avoid this scenario, sight in your shot gun BEFORE opening day. My husband does this by putting up a large sheet of paper. Then, stand 20 yards away. About right, for a grouse hunter. Mount your gun and shoot. Make sure your gun is shooting where it's suppose to. You made need to make adjustments to the stock so the gun shoots where your eye is looking. Practice, and make sure your gun fits you properly. All, so important for a successful hunt.
